WordPress Performance Review Skill

Overview

Systematic performance code review for WordPress themes, plugins, and custom code. Core principle: Scan critical issues first (OOM, unbounded queries, cache bypass), then warnings, then optimizations. Report with line numbers and severity levels.

When to Use

Use when:

• Reviewing PR/code for WordPress theme or plugin
• User reports slow page loads, timeouts, or 500 errors
• Auditing before high-traffic event (launch, sale, viral moment)
• Optimizing WP_Query or database operations
• Investigating memory exhaustion or DB locks

Don't use for:

• Security-only audits (use wp-security-review when available)
• Gutenberg block development patterns (use wp-gutenberg-blocks when available)
• General PHP code review not specific to WordPress
